Debian Policy, 5.6.8:

"Specifying a list of architectures or architecture wildcards other than
any is for the minority of cases where a program is not portable or is
not useful on some architectures. Where possible, the program should be
made portable instead."


I probably focused too much on the last sentence, as I realize now that
this corner case matches exactly the "not useful on some architectures"

Also, at the beginning of my research, I didn't know that only four
architectures supported ACPI, I thought it was supported on all of them
except the ones for which the initial bug report [1] stated a build
failure (armhf, ppc64el and s390x). That's why I was more inclined on
finding a solution to exclude some architectures, than enabling only a
few of them; I didn't want to maintain on the long term a list of
architectures built manually, both for officially and non-officially
supported ones, and both for Debian and Ubuntu (they change nearly over
every release, maintaining it would have been tedious, and a nightmare
to backport).

All in all, I started this journey on the wrong direction, but
everything is clearer now.

Thanks for clarifying that. I think I'll go for the binary package
duplication then.
